I am desighning a control system in a box. I want to add a switch to act as 2 different operating modes.
Mode A is 120VAC. when the level indicator is activated it energizes a relay. 3-wire set up contains 1 power, 2 common, 3 ground
Mode B is a simple 5 VDC npn circuit connected to a microcontroller . When level is reached it activates a motor. 2-wire set up Power (5vdc) and Ground.
I do not want to use a transform so I was looking a SMPS for the npn circuit. What are some options.
Thank you
